IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 174, [89, dated February 29, December'lS, 1875. y'

To all whom tif/nay concern.- v

Be it known that I, PAUL S. BUEDITT, of

Hornellsville, county of Steuben, State of rake-head, &c., showing the manner of attaching the rake-teeth; and Fig. 4 shows a modication in the means for connecting the yield ing roller with the rake heads or arms.

Similar letters of reference denote like parts wherever used. j

My invention relates to the improvement of that class of raking attachments known as a combined rake and reel and to the construction of the rake itself, and consists, first, in the combination, with the rake and reel arms and a single unvarying cam-track or way, of

"meansfor changing the path of the rakeand reel arms, adapting them to act as reelarms only, and to actalso as rakes when desired Without changing the path of the rollersconnecting said arms and with the guiding-cam. It further consists in a novel manner of uniting the rake-teeth to the rake-heads, whereby they are adapted to yield to heavy obstructions such as stumps, stones, or badly-tangled grain, which, being too heavy to be moved by the light teeth employed, are liable to break the latter andto injure or destroy the rake.

In the accompanying drawings, A represents a grain-platform, of the usual quadrant form, and provided at its sides or ends with the usual curved fenders or guards B B'.

The platform, or platform-bar, has its inner endextended beyond the guard B', adapting it to be connected with the machine-truck, or

the platform may be connected through the iinger-bar with the machine-frame in any usual Or preferred manner. Upon this inner eX- tended end A' is secured the rake-standard C, of any suitable construction, and provided 1876; application iiled at its upper end with a fixed stud or shaft, c', upon which the bevel or crown wheel and rake-head D is mounted, and to which motion is imparted through a bevel-wheel, D', from any suitable shaft or wheel on the' machinetruck, and by any preferred arrangement of gearing or chain and band or sprocket wheels. p Upon the upper end of the fixed shaft or stud c', above the crown-wheel, is secured a fixed cam, E, made by preference in the form of an irregularlyshaped bowl, the outerrim of which varies at different points from an undulating horizontal position, as at e e1, to a vertical or nearly vertical position, as at e2, according to the varying position it is desired the reel-arms shall assume in passing around the stud or shaft c', for adapting it to pass over the platform and machine, and for picking 'up the grain and presenting it to the cutters and depositing it upon the platform. To the upper face ot' the crown-wheel D a series 0f rake and reel arms, F, (only one" of which, however, is shown,) are pivoted, to the outer ends of which the rake-heads G are united in any'usual inan-` ner. The upper faceof the arms F have lugs or uprights, f f 1, formed upon or attached to them, in the upper end sof which, upon each arm, is mounted a rock-shaft, h, provided at its inner end with a crank-arm, lil, armed with a friction-roller, H, which rests upon and travels around the upper outer face of the cam E. The rock-shaft h, between the uprights f f1, is surrounded by a coiled spring, i, united `at one end to said shaft and at its other end to one of the uprights, said spring being so arranged as to serve by its tension to hold the crank hl down against a stop onl upright f1, with the roller H at its nearest point of approach to the arm F, as shown in Fig. 3. By this arrangement the arm F is heldl up in close proximity with the lower face Vof the cam or cam-rim, and may be provided,- if desired, with a small fiction-roller moving in contact therewith for relieving the friction. The inner curved guard or fender B', upon its inner or stubble side, is provided with a horizontal flange, ledge, or rail, b, extending from the front to the rear or discharging end of the platform, as shown, and to the forward end of this rail is pivoted an angular oranged latch or 'nger, b1, forming a pivoted'for'ward extension of said rail. portion of this finger is made tapering from rear to front, terminating with the horizontal part in a point at its forward end. This vertical portion is extended behind the pivot, and

the purpose of these spurs being hereinafter explained. Upon the rake head or arm is secured an adjustable plate or arm, g, which projects inward from the rake-head inthe form of a spur, g', which, it' desired, may be provided with a friction-roller, so located upon the rakearm as to be in the same vertical planewith the ledge or rail b when the rake-arm reaches or passes over the forward end of said rail.

The operation of the parts thus described is as follows: Supposing the finger b1 tol bein tl.e horizontal position shown in Fig. 2, when, in the revolution of the rake-arm, the roller H entersthe depression at e in the cam E, for

, enabling the rake-heads vto pick upthe grain,

and present it to the cutters, the spur g passes under the horizontal flange orportion of the finger b1, and when the roller E rises over the inclined portion between e and el of the cam E, the rake-arm is prevented from rising with it, the crank-arm hl overcoming'the tension of the spring t', and permitting the roller to rise while the rake-arm yields to the grasp of the ledge b. ,The further movement of the rakehead brings the spur g into contact with the spur b3 on fin ger b1, and rocking the latter on its pivot causes in to assume the position shown in Fig. l, while the spur g', remaining and moving under the curved ledge b, causes the rake to sweep theplatform, the tension of the spring i lifting the rake out of the grain as soon as the spur g reaches the end of the ledge or rail b1. The nger b1 being now turned down out of the way, as described and as shown in Fig. 1, the succeeding rake-heads will be lifted by the incline from e to e inthe cam E before the spur g reaches the ledge b, and, consequently, such arms will act as reelarms only until another arm, provided with a spur, g', in passing over the ledge b strkes the upper spur b2, and resets the finger b1 -for 'causing the next arm to act as a rake. Thus, the

spur g is made upon one arm to set the fingerv b1 to cause the succeeding arm to act'as'arakearm, while the same spur on the rake-arm turns the finger b1 to allow the arms to'act as reelbeaters only. Thus,'ii` but one arm is used, it will act in one revolution as a rake-arm, and the succeeding revolution as a reel or gathering-arm, and so on alternately. If two arms are used they will act, the one as a rake, and the other as a reel-arm, and if four arms are employedtheyv may act alternately vas rake and reel arms; or, thev reelarm in advance of the rake-arm may be provided with the spur The vertical rib or g', for setting thenger b1, which,the rakearm vacting upon in its turn, again turns out of the path of the succeeding arms, as described.

The finger b1, in practice, will .be held by a 'spring in either position to which it isturned by the spur g', said spring being applied either to the pivot or at the 'rear of the finger, and resting alternately against one of two faces .placed at, or 'nearly at, right angles to'each other, or any convenient arrangement of spring may be used for the purpose.

In Fgql a modification is shown in the manner of applying the roller H to the rake-head.

Thus, instead of its being applied to a crankarm, it is mounted on the inner end of a vibratin g arm, h2, hinged t0 the outer standard f2, and passing through a vertical slot in standard f3, a spring, i", servingto hold the arm at the lower end of said slot, with the roller at its nearest point of approach to the rake-arm, but allowing said rake-arm yto yield or be drawn away from lthe roller when aetedupon byfthe finger bl and ledge b, as described.

The operation of these parts will be readily understood.

From the foregoing description itv will be seenthat with an unvarying cam, and with a guiding-roller follwing said cam in an unvarying path, the rake'and reel arms are made to pursue the diferent paths adapting them to the performance of their respective functions.

The nger b1, besides being operated automatically by the rake and reel arm, as described, may also, by means of a cord, or cord and treadle, be operated by the driver, either for withdrawing vthe finger out of the pathoi the arms lintended to 4act as rake-arms, or for setting it to act upon arms designed to actas reel-arms only, as preferred.

The rake-head G may be of any usual or preferred construction, 'except that to its lower edge a rod, .j, is rigidly connected, extending the whole or nearly the Whole 'length of said head. Upon said rod, at suitable distances apart, and within recesses formed in the lower edge of the head, are placed springs j formed by ceiling the ends of a wire around the rod in Asuch manner as to leave an intermediate loop for the reception vand retention of 'the tooth k. The ends of the spring rest against the lower face of the rake-head, and the teeth being inserted into the loops in front of the rake-head, with the spring under tension, said springs serve to hold the teeth in working position, with the projecting upper ends resting against the forward face of the head, as shown, but allowing them to yield in the event vof their striking against a stump, stone, or other 174,189 Y i f s used, if preferred, and instead ofthe single out changing the path of the rollers, substantially as described.

.2. The combination of the rake and reel arms provided with the yielding or spring guiding-roller with the single cam E, arranged and=- operating substantially as described.

3. The guide rail or Way lb provided with the pivoted latch or finger b1, in combination with the xed guiding-cam E and therakearms, operating substantially as described.

4. The latch or finger b1 pivoted to the forward end of the curved horizontal railor way b, and operated by the rake and reel arms, for

automatically changing the path of said arms, substantially as and for the purpose described.

5. In aharvesterrake, the removable teeth k hinged to the rake-head, and held to their work by means of springs j', substantially as and for the purpose described.
